So at this point, Demi Lovato and Selena Gomez have been friends for over 15 years.

And a friendship that spans over half their lives is bound to have its ups...
@selenagomez THESE are my favorites!!! Haha #saturdaynightfacetimeparty 💗👯💁
...and its downs. Like when Demi was asked why she unfollowed Selena on Twitter and shared this too-real truth:
Or, when T. Swift got roped into the drama.
Demi recently took to Twitter to gush over her BFF's new hit single...
.@selenagomez Loving your new song Fetish, we've come a long way since our Barney days 😝💗
...to which Selena replied with praise for Demi's new bop as well.
@ddlovato Yes we have 😊 -just listening to Sorry Not Sorry! You slay as always. So happy for you!
No competition. No shade. Just love, congratulations, and two talented women supporting each other.
It was a pretty magical moment and Delena fans lapped it up.

Even Apple Music took the time to acknowledge both queens.

In the words of Demi herself...
@selenagomez No matter what we go through, and no matter where we are, nothing and no one can change our friendship. I love you too. :)
